In collaboration with physicist James Freericks of Georgetown University, Sherry Chang and Johnny Chang of the NASA Ames Supercomputing (NAS) Division recently co-authored a paper on some impressive optimization and scaling work done on Freericks’ research code, NDMFTS. The paper describes NAS’ efforts to optimize and scale NDMFTS, ultimately achieving a 7.3-fold speedup and 8.53 teraflops (66% of peak) sustained performance on 2,032 processors–the highest sustained teraflop performance of any application run on Columbia.
